Specification of Letters Patent.

TANK-VALVE.

Patented June 15, 1915 Application filed 0ctober28, 1914. Serial No. 868,959.

To all whom it may concern:

Be it known that I, NATHAN ZIMTBAUM, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Tank-Valves, of which the following is a specification.

This inventor has for his object the production of a valve to be used in flush tanks which will not only serve all ordinary purposes but will, because of certain peculiarities of construction overcome many of the objections found in the ordinary valve.

One of the greatest difliculties with tank valves in common is to keep them from leaking or dripping, the leak or drip not only wastes the water which is particularly objectionable in large cities, but it is annoying by its constant noise and by the fact that it lowers the flushing efficiency of the tank.

My object is to overcome this drip and to accomplish this I provide a valve having a double seat so that the closing of the valve will result in producing a double closure or double contact. 7

Although my device is of simple construction it has in every instance proven eflicient and well adapted to the purpose for which it is meant.

The construction of the device and the operation thereof will be set forth as the specification progresses.

The following is what I consider the best means of carrying out this invention and the accompanying drawings form a part of this specification, in which,

Figure 1 shows in elevation a complete valve. The longitudinally movable cap is raised to disclose the valve seat. Fig. 2 shows a section through a portion of the valve and valve seat and parts adjacent thereto. Fig. 3 is a plan view of the valve seat.

Similar reference numerals indicate like parts in all the figures where they appear.

In describing my invention I desire to call attention to the fact that certain portions, particularly the valve proper and the metallic fitting are of ordinary construction, and

as their operation is fully understood I do not deem it necessary to fully describe them or their functions. I Will however, refer to them whenever necessary by a series of reference numerals.

At 1 I have indicated the interior portion ted line 2, and

of, a valve. This portion which may be tubular, may be considered a guide or outlet member. This member extends upwardly to a distance approximating the dot is provided with a plurality of apertures 3, 4, from its side wall through which the water passes. Arranged over the tubular member 1, is a cap 5, which is free to be reciprocated longitudinally over the member 1. The length of the member 5 is about equal to the required depth of water in the tank, and an opening 6 through the top of the member 1 serves as an overflow to maintain the required level of water in the tank. Arranged at the lower end of the movable member 5 and carried thereby, is the closure for my valve. This consists of a flange projecting from the periphery of the member 5 and extending downward.

The inner face of this closure is arranged at an angle as indicated at 7 and the outer .face may be given any conventional shape.

It will be noted that I have arranged a .weighted projection or addition 8 upon the flange. This may be of lead and I provide it to assist in obtaining a secure closure of the valve.

At 9 I show what I may term my valve seat. It consists of a duplex ring made preferably of soft and pliable rubber. The ring has a body of suiflcient area to furnish a support for a plurality of upwardly projecting flanges l0 and 11. It will be noted that these flanges are not of the same height, the reason for this will appear later. The ring 9 is circular and fits about a portion of the member 1, and the flanges 10 and 11 are extended completely around the ring 9, are each angular in shape so as to produce a soft, flexible compressible edge. The angular portion 7 of the movable flange on the part 5 contacts through gravity with the thin edges of the flanges 10 and 11, and the weight of the member 5, and the parts attached and the leaden portion 8 compress the edges of the flanges 10 and 11, closing the valve at two points, that is on the flange 10 and on the flange 11. Should any irregularity occur in the angular portion 7 or should either of the flanges 10 or 11 become chipped or injured the other flange will serve as a complete and satisfactory closure even though operating independently.

It will be noted that the member 9 is an integral part consisting of the body and the flanges l0 and 11 and that it is moreover in- Q V 1,143,o'14

dependent of the mechanism of the valve,

it being merely placed over and about the member 1 and held thereto by-the friction between its inner periphery and the outer periphery of the member 1. Should thi member or ring 9 or the flanges thereof'ber' come Worn, the part may be readily removed and another perfect member substituted. This is an important factor in the successful use of my invention.

I have described my device as used With a tank valve, but I desire it understood that it may be utilized With many other types of gravity or even compression valves. I also believe that rings of'other materials, but of my general shape and design, might be used successfully. V

Other modifications may be made Within the scope of the appended claims Without departingfrom the principle or sacrificing the advantages of this invention. v

Having carefully and fully described my invention, What I claim and desire to secure by Letters Patent is:

1. A valve having a compressible member provided With a plurality of upwardly extending flanges and an angularly disposed memberoperable therewith, as and for the purpose set forth.

g 2. A valve having a compressiblemember provided vvlth angularly arranged lips and a tapered compressing member operable therewith as herein specified.

3. A valve of the character described hav ing a ring formed ofelastic materiahnp- Wardly projecting and angular lipsformed thereon, and a non-elastic andtapere'd member adapted to engage said lips as and for the purpose set forth. 7

4. A valve having a duplex seat formed of a plurality of tapered and resilientflanges and a tapered non-resilient member adapted to engage either or both of said flanges as and for the purpose set forth.

Signed at New York city in the county of New York, and State of New York, this 15th'day ofrOct, 1914:.
